Linkages among nutrient-associated processes
Across all species, PAP was negatively correlated with PRP (R2 = 0.27, P = 0.049; Fig. 2a), and PRP was negatively correlated with mass loss (R2 = 0.30, P = 0.035). Nitrogen absorption potential was only positively correlated with NRE (R2 = 0.48,P = 0.004), and there were no significant relationships among NAP, NRP, and mass loss (P > 0.05). For AM species, PAP had a significant relationship with PRP (R2= 0.74, P = 0.006; Fig. 2b), and N and P resorption proficiencies were not correlated with mass loss. For ECM species, PAP was negatively correlated with PRP (R2 = 0.86, P = 0.003; Fig. 2c), and PRP was also negatively correlated with mass loss (R2 = 0.68, P = 0.022). Nitrogen resorption proficiency was negatively correlated with mass loss (R2 = 0.72, P = 0.015).
